I'm puzzled about your very detailed description of the setup (very professional, congratulations). Do you mean that lens shift on turrets can change the focus on the screen? I thought that lens shift is only to correct geometry. Are we talking about the same lens shift? I know the one that is available on Cinemeccanica's turrets. I'm also used to the one found on the Home Projectors, I didn't know it's mean for focus adjustments. I know that to change focus you have to slightly rotate the lenses, not just shift them. Am I wrong? Ciao!

The turret stop (how far the turret closes) will help adjust for side to side focus, just like how the gate stop will adjust for top to bottom focus. Cinemeccannica's turret and gate design is not that flexible.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 02-11-2008 02:22 PM                     So I was right, thanks Brad. It's a great improvement. It's like CRT projectors, where you change lenses' angles to achieve correct focus on the entire image. So Christie's gates can be angled vertically to achieve the best focus through the screen... This is missed on Cinemeccanicas. I can only set the stop of the turret (horizontally), nothing on gate. Thanks for your explanation Brad Marco  |  IP: Logged
